This invention-relates to(y supports for incanfdescent lights and, more particularly,v to such supports adapted for the support and connection to electrical circuits of y small incandescentfrzlig-ht in telephone switch-boardsy and the like.: A general object of ,the` invention` isthe 'pro-,- VisOn` of: suchv a. device whichcanbe readily andy economically manufactured, will eiiiciently-snipportand makethe necessary electricalconnecH tions with an incandescent light bulb.' andwhich allowsready-monnting and demounting of the light bulb'with respect to the support.

A more specific object of the invention is the provision in such a device of a pair of resilient metallic members to grip the sides of the base of the light bulb and to make electrical contact therewith and a centering device to` engage the central button of the base of the bulb and make electrical contact therewith, all of whichvcooperate with means to support the tip of the bulb eniciently to support and provide the necessary electrical connections for the incandescent light in a manner to allow its ready mounting and de? mounting; such structure being simple and rugged and requiring a. minimum cost in production.

yA further object of the invention is the provision in such a device of a U-shaped metallic clip adapted to grip the sides of the base of the light bulb and a spring finger interposed between the arms of the U-shaped clip and having an indentation adapted to receive and center the central button of the base of the bulb.

Other objects of the invention will in part be obvious and will in part appear hereinafter.

'Ihe inventionacccrdingly comprises the features of"v construction, combination of elements and arrangement of parts, which willv be exemplifled in thev construction hereinafter set forth and the scope of the application which will be indicated in the claims.

For a fuller understanding of the nature and objects of the invention referencev should be had to the following detailed description taken in connection with the accompanying drawing, in which: y

Fig. 1 is a top plan view, -with parts in section,l of the device of the present invention showing an incandescent light bulb supported thereby;

Fig. 2 is a view on line 2 2 of Fig.` 1, partly in section and partly in elevation;

Fig. 3 is an elevational View of the structure depicted in Figs. 1 and 2; f

Fig. 4 is an elevational view of a panel with che,

partslfbroken away showing ythe bulb-tip support' andmounting clip of thepresent device mounted thereon.

Referring tothe'drawing.. like numerals denote, like prtsfthrouehwt Armadi-,Gfx a` device. in which asis-eel liebt isf-desired., suchY a.- @telg-1 phoepswitchf-brd, is `igm'ividecl with a visualy YQigiplesite,the aperture.,lI;i s ,c `in l2 formed .imma suitable materia'lt'sucliyas; heet-metal, ariclpro vid-@lewin aceatrallwisnesd- Cue-shared per-1 I tion I3 'adapted to/receive the tip of a light rbulb f I4. The bottom of the cup-shaped portion I3 is 15 preferably cut out as shown to allow visibility of the light through the aperture I I in the panel I0. The bulb-tip support I2y is provided witha pair of Oppositely disposed ears v|5-I to aid in the mounting of the bulb-tip support l2. A clip member IG is provided with a pair of.- lingers II-II spaced apart a suliicient distance so that the body of the bulb-tip support I2 may be seated therebetween with the lingers. I'I -I'I engaging the ears I5-I5. The clip member I6 is secured `25 v to the panel in any suitable manner such as by a y screw I8. When the clip member I6 is mounted in position on the panel the bulb-tip support I2 can be readily mounted thereon by slipping the ears I5-I5 beneath the lingers II-I1. j

Directly opposite the structure described above is mounted a bulb-base support I9 including ay base 20, preferably `of insulating material and mounted in any suitable manner on a supporting bracket 2I. A centering spring finger 22 is mounted upon the base 20 in any suitable manner and is provided with a portion 23 having'a face. substantially perpendicular to the axisof the light bulb I4. This face is provided with anindentation 24 adapted to receive and center the central 40 button 25 of the base of the light bulb I4. A pair of spring arms 26-26 are additionally mounted upon the base 20 and disposed on opposite sides of the spring finger 22. The arms 26-26 are of sufhcient length and are shaped to engage and grip opposite sides of the light bulb base 21. In the preferred form, the spring arms 26-26 constitute parts of a U-shaped clip insulated from the spring linger 22 by an insulating washer 28 and held in position on the base 2D together .with 50 the spring finger 22 by a transiixing bolt 29 threaded into the bracket 2I as shown in Fig. 2. l Electrical connection with the light bulb I4 is made by spring arms 26-26 acting as one circuit terminal and the spring linger 22 acting as the 55 other circuit terminal. The resilience of the spring linger 22 and the spring arms 26-26 allow'ready and secure mounting of the light bulb I4, the cup-shaped portion I3 of the bulb-tip support I 2 cooperating with the indentation 24 of the spring finger 22 to properly position the light bulb I 4.

It Will-thus be seen that the device of the pres-- ent invention efiiciently. attains :the 'objectsA set forth above.

Since certain changes may be madenin thef above construction and different embodiments roi? the invention could be made withouteparting from the scopethereof, itis intended that all matter `contained in the above vdescription or shown in the accompanying drawing shall be interpreted as illustrative and sense.

It is also to be understood that the'ilollowingr claims areintendedvto cover all of the generic and specific featuresy of' the invention'herein described, andall statements ofthe scope of the invention which, as a matter of language,- might be said to fall therebetween. Y-

Having described my invention, what I claim asnew and desire tosecure byvv Letters Patent, ist 1. In an incandescent light bulb supportthe combination with a panel having a `visual'aperture therein,

the "visual aperture and permitting light to pass from the bulb through the aperture, a pair of not in a limiting,

ofv bulb-tip supporting .means mounted on said panel -to'support the tip of ay signal light bulb in substantial alignment with" sides of the base of the bulb, a resilient central spaced apart spring arms adapted to grip the bulb contact engaging means disposed between s easing means. i

2. In an incandescent light bulbsupport the i combination with a panel having a visual aperture therein,of an apertured socket mounted on saidapanel to support the tip of a signal light bulb, theaperture in said socket being in substantion alignment with the visual aperture to permit lightvto pass from the bulb through the visual aperture, a U-shaped metallic springclip adapted togrip the sides ofthe base of the'bulb, a spring nger havingl a portionprojecting betweenthe arms of said clip provided with an indentation to 'receive th central contact of the base of the bulb, common means supporting saidclip and said spring finger with the clip arms"A and indentationin saidvnger insubstantial alignment with the visual aperture including Vmeans to insulate i said `finger from said clip, a circuit terminal connected to said clip, and another circuit terminal connected to s aid iinger.
